Short for Roleplaying Game. Table top or otherwise that allows one or more people to assume a fictious alter-personality, or personalities, and live a story while having the ability to make choices to directly alter the experience and/or the outcome.

Not to be confused with most "Japanese console rpg's" or as the kiddies refer to as "RPG-Lite" games such as Final Fantasy, Wild Arms, Dragon Warrior, Secret of Mana, etc. Such games play on the sensationalizing of the term "RPG" to make a buck in the market and in all actuality offer no authentic "Role Playing" experience.
The most they can be described as is simply "interactive anime" or "pop up books with batles".

Isn't it ironic that 99% of console RPG's don't have any actual Role Playing in them?

Similar to a "grenade" but worse. When you have a wing man he can "jump on the grenade". In other words, to distract the ugly best friend but an RPG is so ugly that the only thing a wing man can do is grab his bro and jump out of the way
